15. Um corpo de pequenas dimensões e de 50 kg de massa encontra-se sobre um plano horizontal liso e desloca-se com velocidade escalar constante e de módulo igual a 10 m/s . Em determinado instante, aplica-se a esse corpo uma força vec F , horizontal e oposta ao movimento que o corpo estava descrevendo, com intensidade igual a 100 N. O corpo somente realiza movimento de translação. Determine, em unidades SI: a) a distância percorrida pelo corpo ao fim de 2,0 s, con tados a partir do instante em que se aplicou a força F; b) o intervalo de tempo gasto para que o corpo pare, con tado a partir do instante em que se aplicou a força vec F . 1

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
